Fields

Name	Value	Description
BigInt	1	Exact numeric value with precision 19 (if signed) or 20 (if unsigned) and scale 0 (signed: -2[63] <= n <= 2[63] - 1, unsigned:0 <= n <= 2[64] - 1) (SQL_BIGINT). This maps to Int64.
Binary	2	A stream of binary data (SQL_BINARY). This maps to an Array of type Byte.
Bit	3	Single bit binary data (SQL_BIT). This maps to Boolean.
Char	4	A fixed-length character string (SQL_CHAR). This maps to String.
DateTime	5	Date data in the format yyyymmddhhmmss (SQL_TYPE_TIMESTAMP). This maps to DateTime.
Decimal	6	Signed, exact, numeric value with a precision of at least p and scale s, where 1 <= p <= 15 and s <= p. The maximum precision is driver-specific (SQL_DECIMAL). This maps to Decimal.
Numeric	7	Signed, exact, numeric value with a precision p and scale s, where 1 <= p <= 15, and s <= p (SQL_NUMERIC). This maps to Decimal.
Double	8	Signed, approximate, numeric value with a binary precision 53 (zero or absolute value 10[-308] to 10[308]) (SQL_DOUBLE). This maps to Double.
Image	9	Variable length binary data. Maximum length is data source-dependent (SQL_LONGVARBINARY). This maps to an Array of type Byte.
Int	10	Exact numeric value with precision 10 and scale 0 (signed: -2[31] <= n <= 2[31] - 1, unsigned:0 <= n <= 2[32] - 1) (SQL_INTEGER). This maps to Int32.
NChar	11	Unicode character string of fixed string length (SQL_WCHAR). This maps to String.
NText	12	Unicode variable-length character data. Maximum length is data source-dependent. (SQL_WLONGVARCHAR). This maps to String.
NVarChar	13	A variable-length stream of Unicode characters (SQL_WVARCHAR). This maps to String.
Real	14	Signed, approximate, numeric value with a binary precision 24 (zero or absolute value 10[-38] to 10[38]).(SQL_REAL). This maps to Single.
UniqueIdentifier	15	A fixed-length GUID (SQL_GUID). This maps to Guid.
SmallDateTime	16	Data and time data in the format yyyymmddhhmmss (SQL_TYPE_TIMESTAMP). This maps to DateTime.
SmallInt	17	Exact numeric value with precision 5 and scale 0 (signed: -32,768 <= n <= 32,767, unsigned: 0 <= n <= 65,535) (SQL_SMALLINT). This maps to Int16.
Text	18	Variable length character data. Maximum length is data source-dependent (SQL_LONGVARCHAR). This maps to String.
Timestamp	19	A stream of binary data (SQL_BINARY). This maps to an Array of type Byte.
TinyInt	20	Exact numeric value with precision 3 and scale 0 (signed: -128 <= n <= 127, unsigned:0 <= n <= 255)(SQL_TINYINT). This maps to Byte.
VarBinary	21	Variable length binary. The maximum is set by the user (SQL_VARBINARY). This maps to an Array of type Byte.
VarChar	22	A variable-length stream character string (SQL_CHAR). This maps to String.
Date	23	Date data in the format yyyymmdd (SQL_TYPE_DATE). This maps to DateTime.
Time	24	Date data in the format hhmmss (SQL_TYPE_TIMES). This maps to DateTime.
